1. "Signal Intelligence and World War II: The Unfolding Story." Journal of Military History 63, no. 4 (Oct. 1999): 939-951.

The author tracks the opening up of information from U.S. and UK sources (and secondarily from other countries) about the role of Sigint in World War II.

This work has 828 annotated bibliographic entries dealing
with the role of ULTRA and MAGIC. Entries include both primary and secondary
sources, and the annotations average 4-5 lines each. There are also entries
on sources on the Sigint and cryptanalytic programs of the Axis and neutral
powers. The brief (18 pages) introductory essay is worth reading for its
general sweep across some of the main sources.
